Sony PlayStation Store and Plus Content Manager Chris Howe is here with the PS Plus content for September, which includes Assassin's Creed III, Jak and Daxter Trilogy and more below!

To quote: Hi everyone! We've got a fantastic month lined up on PlayStation Plus for September and if you visit the PS Store and purchase a one year membership anytime between 21st August and 20th September we will give you an additional 90 days at no extra cost, meaning you get 15 months of PS Plus for the price of 12 (€49.99/£39.99)!*

New PlayStation 3 games:

I'm sure many of you caught the announcement during the Gamescom press conference but if not, I am exceptionally happy to announce that this September PS Plus members will have access to Ubisoft's incredible Assassin's Creed III from 28th August.

Assassin's Creed III invites you to experience the untold story of the American Revolution through the eyes of a new Assassin, Connor, son of a Native American mother and British father.

You will meet legendary heroes of American history, and together you will conspire to annihilate those who threaten Liberty itself.

Next up, we welcome all action heroes Jak and Daxter to the service. In typical PS Plus fashion, we're not just give you one title - we're giving you the trilogy!

That's right, next month you will get our dynamic duo's first three adventures Jak and Daxter: The Precursor Legacy, Jak II and Jak 3. Make sure you check them out - I'm sure you will not be disappointed!

Your final PS3 offering for this month is Stealth Inc: A Clone in the Dark, a fast-paced stealth platformer with over 80 levels, featuring brutal hazards, ruthless enemies, fiendish puzzles and red pixels galore.

Armed with only your wits and a pair of top-of-the-line stealthing goggles, it's your job to sneak your way through a deadly facility that's determined to extinguish your fragile little life.

New PS Vita games:

First up for PS Vita is Urban Trial Freestyle. Grab your motorbike and make your way through levels of varying obstacles as you try to stunt your way through the game! Graphically this game looks superb on the PS Vita screen and ultimately it's just great fun!

Last but certainly not least - there have been a lot of calls for this one, so I am pleased to say Konami's New Little King's Story will be joining PS Plus this month. Assume the role of 14-year-old King Corobo tasked with reclaiming his kingdom from an invader known only as 'The Nightmare'.

The evil presence is running havoc and the populace lives in fear as it preys on them. Thus, as young King Corobo, the user must unite their subjects in order to fight back and reclaim the kingdom.

Don't forget that from today, for one week only, PS Plus members also have exclusive access to the Killzone Mercenary beta and Puppeteer demo. Don't miss out!

If you are not currently a Plus member, visit our PlayStation Plus site to find out more about the service. Here you'll learn all you need to know about a one year subscription to the Instant Game Collection all for a one-off payment of just £39.99 / €49.99.

Remember, if you've not got access to your PS3 or PS Vita then you can also buy through our online store. *Please note offer applies for purchases via the PlayStation Store only. Existing users are able to stack their membership.
